Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure of a holding concrete for temporarily fixing a jointing material of a holding concrete provided on the upper surface of a slab such as a rooftop with a heat insulating layer interposed therebetween, and in particular, without using mortar. The present invention relates to a support structure for joint material that can be supported on.

[0002]

2. Description of the Related Art The top surface of a slab such as a rooftop is waterproofed, and then a concrete presser is placed on the waterproof layer with a heat insulating layer interposed between them to enhance the heat insulating effect. In this case, the top surface of the holding concrete should be sloped so that rainwater can be drained smoothly. For this reason, it is necessary to provide a slope on the upper surface of the joint material of the holding concrete.

As shown in FIG. 10, in the conventional joint material, a cap 52 is put on the upper end of the joint material 51, and support legs 53 are detachably attached to both side walls of the cap 52.
After adjusting the degree of inclination of the support leg 53 to adjust the height so as to match the above-mentioned gradient, the joint material 51 is temporarily fixed by mortar 54 as shown by a chain line in the figure. .

As another method, as shown in FIG. 11, the joint material 61 is inserted into the fixed base 62 on the heat insulating layer A to stand upright, and the height is adjusted according to the insertion condition, and then the above is performed. In the same manner as in (1), mortar 63 is used for temporary fixing.

By the way, in the former supporting method, the joint material 5 is used.
Since 1 is suspended in the air, it is unavoidable to fix it with the mortar 54, but in the latter case, if the fixing base 62 is fixed to the heat insulating layer A with an adhesive tape or the like, the mortar 63 is dared.
Seems like it doesn't have to be fixed in.

However, the support stability of the upper portion of the joint material 61 is poor, and if an object hits it, it will be displaced, so it must also be fixed with mortar 63.

As described above, no matter which of the above support structures is adopted, it is necessary to temporarily fix and fix the mortar 54 and 63, and it is troublesome to support the joint materials 51 and 61.

Further, when placing the presser concrete, a curing sheet such as a plastic sheet is laid on the upper surface of the heat insulating layer A as shown by a chain line S in FIG. 10 so that the concrete (mortar 54, 63) does not enter the heat insulating layer A. There is. In this case, the fixing of the support leg 53 and the fixed base 62 to the heat insulating layer A is performed by adhering a tape or the like, and the adhering is performed by the curing sheet S
Since the entire surface of the curing sheet S is not fixed to the heat insulating layer A, the fixing position may move due to the partial displacement of the curing sheet S. Furthermore, if sweating occurs on the upper surface of the heat insulating layer A due to dew condensation or the like, sufficient fixing cannot be achieved by adhesion.

Therefore, an object of the present invention is to eliminate the need for troublesome temporary fixing with mortar.

[0010]

In order to solve the above problems, according to the present invention, first, a lower part of the joint material is vertically movably fitted into a base fixed to the heat insulating layer and a cap is covered. bonding the joint material upper at any position of the heat insulating layer, with at the pin or stapler needle supported by fixable legs, the legs are on either side of the joint member, calibration
Diagonally downward straight line from the top end on the top side to the bottom end on the heat insulation layer side
It adopted a configuration that is similar to the above.

Further, the lower part of the joint material is fixed to the upper surface of the heat insulating layer, and a cap is fitted on the upper part of the joint material so as to be movable in the vertical direction, and the cap is adhered to an arbitrary position of the heat insulating layer , a pin or a staple of a stapler. It is supported by a leg that can be fixed , which is located on both sides of the joint material and
From the top end on the cap side to the bottom end on the heat insulation layer,
It is also possible to adopt a linear configuration.

Further, in the one in which the pressing concrete is placed with the curing sheet interposed on the upper surface of the heat insulating layer, the leg is fixed to the pin or the needle of the stapler and the curing sheet is set.
It may be fixed to Mase write eating in the heat insulating layer through the door.

[0013]

According to the present invention thus constructed, the height of the upper surface of the cap, which is flush with the upper surface of the pressing concrete, is adjusted by the degree of fitting of the joint material to the fixed base, and then the upper portion of the joint material is supported. Secure the legs to the insulation. That is, the upper and lower parts of the joint material whose height is adjusted are supported by the heat insulating layer by the fixed base and the legs.

Further, the height of the upper surface of the cap, which is flush with the upper surface of the pressing concrete, is adjusted by adjusting the degree of covering the upper part of the joint material with the cap, and then the cap is supported and fixed by fixing the legs to the heat insulation layer. To do. That is, the upper and lower parts of the joint material are supported by the heat insulating layer with the caps and legs and directly.

In the case where the curing sheet is interposed, since the sheet is directly fixed to the heat insulating layer through the sheet, the above-mentioned fixings are surely made and there is no fear of movement. In addition, there is no problem even if sweating occurs.

In any case, the present invention is
The upper part of the ground material is supported by legs on both sides, and the legs are
Since it is a straight line that is diagonally facing, its support is stable. on the other hand,
Lower part of joint material is supported by fitting to base or fixing to heat insulation layer
I do. Therefore, the joint material is the heat insulation layer with its upper and lower parts.
Since it is securely fixed to the mortar,
There is no need to temporarily fix it.
